In vivo gene transfer into the adult mammalian central nervous system by continuous injection of plasmid DNA-cationic liposome complex.
Previously reported methods of liposome-mediated direct in vivo gene transfer have been inefficient, especially when performed with highly differentiated, quiescent cells of the adult mammalian central nervous system (CNS). We have therefore improved these procedures based upon a novel concept. Following continuous injection of plasmid DNA-cationic liposome complex which contained a reporter gene encoding E. coli beta-galactosidase into the striatum of adult rats, the expression of transgene was dramatically elevated without any adverse effects. This new technique may enable a wide application of liposome-mediated gene transfer technology not only to basic analysis of gene functions in the brain but also for clinical treatment of certain CNS disorders.
